Columnar processing for SQL-on-Hadoop: The best is yet to comeWang Zuo
Apache Parquet is an open-source file-format which arranges all of its data into columns – this is distinct from the traditional row-oriented layout, which stores entire rows consecutively. Columnar data offers lots of advantages to modern data engines – like Impala, Apache Spark, and Apache Flink – in terms of IO efficiency, but the full benefits of the format are yet to be realized.
We have been working with Intel to apply modern CPU instruction sets to the common programming tasks associated with querying data in Parquet format: decompression, predicate evaluation, and row-reconstruction. Our work has yielded significant speedups in standard query benchmarks running on Cloudera’s Impala SQL query engine, and very high speedups in targeted microbenchmarks.
In this talk we’ll describe the symbiosis between modern CPU architectures and the requirements of columnar data processing. We’ll show how vectorization – processing many items with a single instruction – is a widely applicable technique that can provide real performance benefits to all application frameworks that use columnar formats. We’ll present the changes that we have made to Impala’s ‘scanner,’ which reads Parquet data, and map out even more future enhancements.
This talk will be of interest to audiences interested in the internals of big data processing engines, or the impact of recent advances in modern CPU architectures.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
